How long does it take to sharpen a pair of skates?

Average rental/retail sharpening is 3-5 cycles equaling 2-3 minutes per skate or 4-6 minutes per pair. With two heads found on the Sparx Sharpener Commercial Dual (PS200 Dual) you can sharpen twice as fast and sharpen a pair of skates in 2-3 minutes.

Can the sharpener handle high volume usage?

Yes, the Sparx Sharpener Commercial (PS200) and Sparx Sharpener Commercial Dual (PS200 Dual) are both designed to handle high volume usage.

Does the Sparx Sharpener profile skates?

The Sparx Sharpener will not contour the profile of the blade. But, unlike traditional manual sharpening which alters the profile after each sharpening, the Sparx Sharpener will hold the skate profile throughout the life of the steel thanks to the consistent RPM, Speed, and Pressure applied by our Grinding Rings.

When I'm sharpening, should I have the toe pointing left or right?

Both ways will work. However, some people prefer to have a higher contact point on the toe of their skate, so we recommend facing the skate toe to the right to ensure the contact point is getting high enough on the toe. Either way, the finish will be smooth and this won't affect performance.

How many passes should I choose when sharpening?

If you are freshening up your blades after every skate, 1-2 cycles will usually be enough. If you’re sharpening your skates after every 5-6 hours of ice time, you’ll typically want to run 4 cycles. If you’re changing your radius or have new steel, you will need about 10 cycles.

Can I use the Sparx Sharpener in cold weather?

We recommend the sharpener be used in temperatures above 40 degrees F for optimal performance.

Can I travel with my Sparx Sharpener?

Yes. Portability is one of the best features of the new Sparx Sharpener.

Can you sharpen goalie skates?

Do you offer a Flat Bottom sharpening?

Yes! Our patented FIRE (Flat Inside Radius Edges) Ring produces a flat bottom hollow.

How do I know which Grinding Ring to choose?

While there are many options available, the most common grinding rings are the 1/2" and the 5/8" Radius Ring™. Through our testing, we have determined that a 1/2" Radius Ring is a great starting point for smaller, younger players. Many adult players skate on a 1/2" radius as well. We have, however, found that larger, heavier players actually do quite well on the 5/8" radius. A flatter radius, the 5/8" allows heavier players to sufficiently grab an edge for turning and stopping but provides great glide as more of the blade remains above the ice surface.

What is the difference between a Radius Ring™ and a FIRE Ring™?

The easiest answer is that the Radius Ring™ produces a traditional "radius of hollow" (ROH) sharpening. Unless you know you skate on a flat-bottom profile, you will likely want to choose the Radius Ring at checkout. The Radius Rings work for both player skates and goalie skates. The FIRE Ring™ produces a flat-bottom cut with radius edges. You can find more information on the Grinding Rings page or in this blog post.
